Description
A local privilege escalation vulnerability exists in the Restricted Access (Kiosk) Mode implementation of Scheidt & Bachmann entervo HMI prior to V2 R5 P0 M5. The vulnerability affects the external PDF viewer functionality used to display the application manual and its interaction with the underlying Windows operating system.
